Adjustable cap

ABSTRACT

An adjustable cap comprising a grip and a hub is coupled to the grip. Wherein the grip and the hub are configured to rotate independently of each other and a plurality of legs is coupled to the hub and a lock coupled to the hub wherein the hub and the lock are configured to rotate independently of each other. The lock is further configured to move the legs toward a center of the lock and a cap thread is coupled to the hub wherein the cap thread is configured to move down when the grip is rotated. A plate is coupled to the cap thread wherein the plate is configured to rotate independently of the cap thread. The adjustable cap provides a seal on multiple bottle opening sizes that can be used with a tube to withdraw fluid.

BACKGROUND OF THE INVENTION

Staying hydrated during exercise such as bike riding, hiking, walking or running is essential for peak performance. Hydrations systems are available that can deliver fluids to a person while they are exercising through a tube. The tube allows a person to continue to exercise and drink at the same time. Due to the movement created by the exercise, the fluid must be in a sealed container to prevent fluid from escaping while being moved. Existing hydration systems provide a specific sealed reservoir for liquid with a tube that is used to withdraw the liquid. This is a limitation in that existing hydration systems will only function with the fluid reservoir provided with the system.

Bottles containing beverages such as sport drinks, juice, water and sodas are manufactured with a wide range of bottle top openings. A sealed adjustable cap is needed that can be placed on multiple bottle top openings, provide a seal, and allow fluid to be withdrawn with a tube. This will allow a person to use a typical type of bottle in a hydration system. The adjustable cap can fit on multiple bottle openings and allow fluid to be removed with a tube.

DETAILED DESCRIPTION

FIG. 1 is a perspective view the adjustable cap. Adjustable cap 4 comprises grip 8 connected to hub 12 which is connected to lock 14. Grip 8, hub 12, and lock 14 are connected such that all can rotate independently of each other. In one embodiment each grip 8 snaps into hub 12 wherein grip 8 and hub 12 can rotate with respect to each other and stay connected. Cap thread 30 is inserted into grip 8 and comprises check valve 22 and hole 18. Tab 26 and tab 34 keep cap thread 30 in the same rotation as grip 8.

FIG. 2 is an exploded view of the adjustable cap. Slot 42 and slot 46 match with tab 26 and tab 34. Cap thread threads 38 extend below grip 8 and thread into hub threads 58. When grip 8 is rotated, cap thread 30 will move up or down in relation to hub 12.

Legs 50 are located in slots 54. Slots 54 allow legs 50 to rotate in and out from the center of lock 14. Lip 52 is located at the bottom of legs and allow legs 50 to grip to an edge. Wedges 62 are positioned on the inside edge of lock 14 and rotate legs 50 in or out based on the direction lock 14 is turned.

FIG. 3 is an exploded view of the cap thread. Gasket 66 provides a seal between top plate 68 and bottom plate 74 to prevent fluid from escaping between the two plates and seals around hole 18. Bottle gasket 70 is located on the bottom of top plate 68 and is placed around bottom plate 74. Check valve tube 78 consists of a simple check valve comprising ball 82 and spring 86. As fluid is removed from a bottle the spring 86 compresses, allowing air into the bottle. When no fluid is removed from the bottle, spring 86 and ball 82 form a seal to prevent fluid from leaving the bottle.

FIG. 4 is a side view of the adjustable bottle cap. Adjustable cap 4 placed on top bottle 94. Lock 14 is rotated such that wedges 62 allow legs 50 to fit over edge 98. Lock 14 is rotated and wedges 62 press lip 52 under ledge 98. When bottle 94 is secure and cannot be pulled away form adjustable cap 4, grip 8 is rotated and cap thread 30 presses large gasket 70 into the top of bottle 94 creating a seal. Top plate 68 and bottom plate 74 can rotate independently of cap thread 30. This allows large gasket 70 to be compressed tightly against the top of bottle 94 without movement between large gasket 70 and top of bottle 84. While cap thread 30 is rotated to create compression on the top of bottle 94, large gasket 70 does not rotate. Straw 90 can then be inserted through hole 18 to remove fluid from bottle 94. The adjustable cap 4 can be adjusted to fit a variety of bottle opening sizes and still maintain a seal.

FIG. 5 is a side view of the adjustable cap. Section A-A is a cross section of the adjustable cap 4 on bottle 94.
